We’re not going to lie. We were a tad skeptical when Barney and Robin finally got together on How I Met Your Mother. But, to be honest, we’re more invested in them than we are with Ted and his search for the elusive mother of his children! Tonight, Barney and Robin have their first fight and go to Lily and Marshall for advice. Just a hunch, but we think they may regret that decision!

On Gossip Girl, Olivia (Hilary Duff) appears on Jimmy Fallon’s show and does everything possible to make sure that Dan doesn’t hear what she said. Was it something about him? And you know, for a character that’s supposed to be a “movie star trying to be normal by going to college,” she still does a lot of Hollywood things! On another note, we sorta like that Blair and Serena are at odds yet again—tonight things heat up when Blair befriends another “it girl” to make S jealous!

And, over on VH1, Diddy is looking for more poor souls that want to to be tortured, er, employed by him on a new season of I Want To Work For Diddy. Off the bat, the new applicants are made to suffer through a lousy night’s sleep.
